All X sub codes have been deprecated and removed from registers.
I01 and I02 remain unchanged.
The DfE (Department for Education) no longer advises schools to record pupils who do not attend for reasons related to COVID-19 using Code X.
Where a pupil is not attending because they have symptoms of COVID-19 or have had a positive test, schools should record this using Code I (illness) unless another more appropriate code applies.
Schools may continue to use the sub-code (I02) to record illness due to suspected COVID-19 although they are not required to.
You can find the full DfE guidance here.
